i tried using Chrome and Fire fox but nothing changes

I don't have any problems, running Safari on Mac OS X Snow Leopard. I don't know if it's usual or just for once, but, in the second case, maybe that was an unexpected error from the server.
Please tell us more, so we'll can help you ^^'

Maybe the thumbnail server was behind? Try looking at where the thumbnail loads from next time. Sometimes we switch from thumbnail servers to test load or do maintaince on the main thumbnail server. This might decrease performance but should still load the thumbs slowly.
